ABSTRACT

Maternal input addressed to children after an early hospitalization (EH) was longitudinally compared to maternal input directed to typically developing children (TD), at 6, 9, 12, 18 and 24 months of age. The data were analyzed with the CHILDES tools for (a) word-tokens (b) word-types (c) Mean Length of Utterances (MLU) and (d) questions in which the mothers request a response or a turn. Nonsignificant differences between groups were found. Only questions were significantly higher for EH mothers than for TD mothers across the five sessions. Lexical Correspondence Analysis (LCA) on these two datasets show qualitative differences between the two groups. Depression and anxiety at 12 months and children attachment behaviour assessed at 18 months do not play a role from EH mothers. These findings suggest that EH mothers have a specific conversational style encouraging their infants and toddlers to request salient information or to perform an action.

摘要

将早期住院 (EH) 后针对儿童的母亲投入与针对 6、9、12、18 和 24 个月大的典型发育儿童 (TD) 的母亲投入进行纵向比较。使用 CHILDES 工具对数据进行了分析，用于 (a) 单词标记 (b) 单词类型 (c) 平均话语长度 (MLU) 和 (d) 母亲要求回答或转身的问题。发现组间差异不显着。在五个疗程中，只有 EH 母亲的问题明显高于 TD 母亲。这两个数据集的词汇对应分析（LCA）显示了两组之间的定性差异。12 个月时的抑郁和焦虑以及 18 个月时评估的儿童依恋行为对 EH 母亲没有影响。这些发现表明，EH 母亲有一种特定的对话方式，鼓励他们的婴幼儿请求重要信息或执行某项行动。
